This invention relates to new and useful improvements in devicesforapplying medicinal powder to different body orifices, and has for itsprimary object to provide a relatively simple and easily operable devicewherein the powder may be delivered to predetermined point within theorifice and thence properly discharged.

A further and important object of the invention is to provide meanswhereby powder cartridges ma be injected into the device and thencedelivered to the infected parts, after which the powder may be forciblyprojected from the cartridge. By reason of the provision of such acartridge, the medicinal powder may be conveniently sold to the trade,and such'powder may be readed within .the applicator without any liaility of the projected from the device until such is the intention ofthe using party or attending ph 'sician.

ith the foregoing and other objects in view as the nature of theinvention will be better understood, .the same comprises the novelform,-

of parts hereinafter more" fully described,

combination and arrangement shown in the accompanying drawing andclaimed. 4

In the drawing wherein like reference characters indicate correspondingparts throughout the several views? Figure 1 is a detail longitudinalsection through my improved medical powder applicator, a powdercartridge being shown as arranged therein and the gwder being diseclosed as being projected erefrom,-and

Figure 2 is a perspective of a powder cartridge that is preferablyused'in carrying out. the present invention.

Now. having particular referenceto the drawing, my; novel applicatorconsists of a relatively elongated cylinder of small diamconstructed ofany suitable mateeter rial. The inner end of the same formed with anoutwardly extending c1rcumferential'flange 6 so finger attachment atthis 'end of 'the cyl inder. v r .I

The opposite end of the cylinder is formed with an internalcircumferential. lip 7, while slidably' arranged within this cylinder isan elongated iston 8, the inner end of which is rovid with a reducedstem 9 having is a pin-point 10 upon the inner endthereof.

same spilling or being as to provide a,-

In carrying out the present invention, there is provlded a heavy paperor cardboard cartridge 11 ofcylindricalformation and beingof a diametersuch as to permit of the free movement of the same within the cyl- 6Qinder 5. The top wall of this cartridge is composed of thin paper 12having cross per-- forations 13 therein in order that this paper may beeasily broken when pressure is applied to the medicinal powder 14therein. Arranged within the lower end of thecy- "lindrical cartridge isa plunger-like wad 15 that will be impaled upon the pin 10 of thereduced stem 9 of said piston 8 when the "same is forced thereagainst,it-being obvious that the reduced stem 9' is for the purpose ofpermitting the same to pass into the body of the cartridge during theprojection of the powder therefrom. Obviously after the pin 10 has beenforced through the wad 15 a further pressure upon the outer end ofthepiston 8 will cause this wad to so act against the powder 14 within thecartridge as to cause the breaking of the wall 12 and the resultantprojection of the powder therefrom so1 as suggested in F1gure 1.

For purposes of facilitating the properactuation of the piston 8 theouter end thereof maybe and preferably is formed with adisc-like head 16to be engaged by the palm 5 of the hand directly beneath the thumbthereof.

It will thus be seen that I have provided a highly-novel, simple andinexpensive medical powder applicator that is well adapted for all thepurposes heretofore designated, and eventhough I- have herein shown anddescribed the invention as consisting of certain detail structuralelements it is nevertheless to be understood that some changes may Q bemade therein without affecting the spirit and scope. of the appendedclaims.

Having thus described the invention, what I claim 1s: f

1. In; medical powder applicator, where- 00 in the powder is disposedwithin a cartridge having-a disruptible closure at one end and a wadd'edclosure at its opposite end, a tubular cylinder for receivmg saidcartridge, means inthe forward end of the c linder. to 1 5 prevent thepassage of the cartri go therethrough, a piston slidable within ecylinder, and means at the inner end of the piston for engaging said wadand for engagement within the cartridge when the piston no is'forcedinto the cylinder so as to force the wad inwardly causin the breaking ofthe disruptible end of said cartridge.

2. In a medical powder applicator for use in applying powder toali'eoted body within a cylindrical cartridge, the outer end within acylindrical cartrid e, the outer end thereof being closed b a isruptiblematerial, and the inner en thereof being closed y a wad, a cylinder forreceiving said cartridge, means at the forward end of the cylinder toprevent the passage of the cartridge therethrough, and a piston slidablymounted within the cylinder and adapted to engage the wad of thecartridge to force the same inwardly of the c lindrical shell forbreaking said disruptib e closure.

3. in a medical powder applicator for use in applying powder toaffectedbody orifices wherein the powder is arranged within acylindrical cartridge, the outer end thereof -means at the forward endof the cylin er to prevent the passe e of the cartridge therethrough, apiston shdable within 'the cylinder and havin a reduced inner end forengagement within the cartridge shell and for engagement with thecartridge wad whereby a pressure of the iston will cause the inwardmovement of t e wad to break the disruptible closure so that a furthermove ment of the piston will discharge the powder from the cartrid e.

In testimony w ereof I afiix my signature.
